1. A method of operating an audio device configured to be inserted in an ear canal, the method comprising:

  • measuring sound pressure levels (SPLs) for at least one electrical drive signal directed to an ear canal receiver (ECR) during a time period Δ

    t having a plurality of samples;

    determining a SPL dose of the at least one electrical drive signal during the time period Δ

    t using the measured sound pressure levels;

    simultaneously estimating an ambient SPL dose within the ear canal during the time period Δ

    t;

    calculating a total SPL dose of the audio device using the SPL dose of the at least one electrical drive signal and the estimated ambient SPL dose; and

    performing an action by the audio device when the total SPL dose is greater than a predetermined threshold.
